A. E. Housman - Say, lad, have you things to do lyrics

XXIV Say, lad, have you things to do? Quick then, while your day's at prime. Quick, and if 'tis work for two, Here am I, man: now's your time. Send me now, and I shall go; Call me, I shall hear you call; Use me ere they lay me low Where a man's no use at all; Ere the wholesome flesh decay, And the willing nerve be numb, And the lips lack breath to say, "No, my lad, I cannot come."
